Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sensor fault detection is implemented with direct control handover, then driving safety is compromised due to sudden control transfer, but maintaining autonomous driving requires continuous sensor reliability

Engineering Contradiction:

Improvedriving safetyVSAvoidautonomous driving experience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system divides sensing sectors into multiple regions and establishes confidence levels for each sector before faults occur. When a sensor fault is detected, the system gradually reduces autonomous driving actions in affected sectors rather than immediately handing over control, cushioning the transition to protect both safety and user experience

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The system dynamically adjusts the confidence levels and autonomous driving action execution strategies based on real-time sensor fault conditions. The execution strategy transitions from allowing full autonomous actions to prohibiting new actions while allowing completion of ongoing actions, creating a flexible, adaptive response to sensor failures

Inventive Principle:

Principle #15Dynamics

2Productivity

If sensor fault tolerance is increased to maintain autonomous driving, then the risk of executing actions based on faulty sensing information increases

Engineering Contradiction:

Improveautonomous driving function levelVSAvoidsensing information accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The sensing space is segmented into multiple sensing sectors, each with its own confidence level. This allows the system to maintain autonomous driving in sectors with high confidence while restricting or prohibiting actions in sectors with low confidence due to sensor faults, thus maintaining productivity without compromising reliability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different execution strategies are applied to different sensing sectors based on their specific confidence levels. High-confidence sectors allow full autonomous actions, medium-confidence sectors allow completion of ongoing actions, and low-confidence sectors prohibit new actions, creating a localized quality approach to fault tolerance

Inventive Principle:

Principle #3Local quality
